本文研究了TCP拥塞控制下的网络，其中每个用户的流的数量是显式考虑。我们提出了一个控制法，这个变量，结合拥塞控制，诱导作为平衡的社会福利最大化的用户水平，而不是TCP连接的水平。我们使用流体流动模型来证明整个系统的动态稳定性定理，结合动态的流量与拥塞控制的动态速率和价格。然后，我们开发了一个准入控制策略的离散TCP流，模拟连续的行为，并建模为马尔可夫链。我们提出了整个系统的仿真研究，表现出其稳定性和所需的用户级的公平行为。
This paper studies a network under TCP congestion control, in which the number of flows per user is explicitly taken into account. We present a control law for this variable that, in combination with congestion control, induces as equilibrium the maximization of social welfare measured at the level of users, rather than the level of TCP connections. We use fluid flow models to prove stability theorems on the dynamics of the overall system, combining the dynamics of flows with the dynamic rates and prices of congestion control. We then develop an admission control policy for discrete TCP flows, that emulates the continuous behavior, and is modeled as a Markov chain. We present simulation studies of the overall system, which exhibit its stability and the desired user-level fairness behavior.
